希望这有助于更好地理解它的工作原理您可以从silverlight toolkit网站下载示例。这里有一个很好的按字母顺序分组的例子，其中包含所有您需要的类和体系结构解决方案。实际上，我正在下载示例工具包，但其中有一些硬代码数据需要传递。。。。。。我正在尝试从rest服务获取数据并绑定到长列表选择器Orry。。。但这不起作用。。。。事实上，如果你看到Silverlight for Windows Phone Toolkit源代码和示例-2011年8月，我发现他们使用longlistselector，但它是硬编码的，我想动态调用rest服务和分组字母CallyRight，所以很明显，你的问题是你对C编程一无所知；-您需要仔细阅读ObservableCollection的用法。正如您所注意到的，如果您读取LongListCollection的源代码，它是一个可观察的集合，如果您添加/删除它，它将自动更新。现在，去读一些东西！这就是为什么像我这样的通用实现要漂亮得多。必须在域模型上实现特定于用户界面的代码是疯狂的！
